BED-BOTTOM.

Specification of Letters Patent No.

To all whom it may concern Be it known that I, B. F. S. MoNRon, ofUtica, in the county of Oneida and State of New York, have invented anew and useful Improvement in Spring Bed-Bottoms, which improvement isalso applicable to seats for chairs, sofas, and all articles or workwhere springs are employed for upholstery purposes; and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the annexed drawings, making a part ofthis specification, in which- Figure l, is a vertical section of abedbottom constructed according to my invention. Fig. 2, is a horizontalsection of ditto, taken in the line as, as, Fig. l.

Similar letters of reference indicate corresponding parts in the twofigures.

The object of this invention is to allow the outermost rows of springsin a bed bottom, chair seat, or other article in which they may beplaced, equal freedom of movement with the innermost springs without anylateral play, so that each spring will be permitted to bear itsproportion of weight, and, while being kept in proper position, allowedto yield or give to the full extent of its movement, thereby renderingthe article in which they are placed far more elastic, durable andaltogether more desirable in every respect, than any of those hithertoconstructed that have. passed under my observation.

To enable those skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents a rectangular frame in which a series of slats a, areplaced, which form seats for springs B, the latter being secured to theslats or seats. The spril'igs B, may be constructed in the usual way, orbe of such form as is generally used for npholstery purposes and whichare plainly shown in Fig. l.

C, is a rectangular frame on the upper part of which a mattress D, issecured. This mattress may be constructed in the usual or in any properway and therefore does not require a minute description. The upper endsof the springs B, are attached to 22,742, dated J' anuery 25, 1859.

the bottom of the mattress D, as plainly shown in Fig. 1.

The two frames A, C, are covered all around by any suitable fabric E,and the said frames within the fabric, and at each side, are connectedby cross bands of webbing F, as shown in Fig. 1, the webbing beingattached to the corners of the frames, each band F, being attached atone end to a corner of the lower frame A, the opposite end beingattached to an opposite corner of the upper frame C.

The parts arranged as above described form a bed bottom, and it will beseen that each spring is perfectly free to yield or give to its fullestextent, the fabric E, of course folding as the springs B, arecompressed, and the cross bands F, preventing the springs l, from movinglaterally in either direction, confining them strictly to a verticalmovement.

The difficulty attending the bed-bottoms, chair seats, &c., as hithertoconstructed is, that the springs are placed in permanent boxes or withinrigid frames which prevent the outermost rows of springs from beingacted upon, the central springs sustaining the greatest part of theweight and eonsequently being the chief dependence of the bedebottom orseat. It will readily be seen therefore that my invention possessesimportant advantages over the old inode of construction, as every springis free to act and each made to bear its proportion of weight, therebyrendering the bed-bottom or other article more elast-ic and durable thanthose hitherto constructed,

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is,

The two frames A, C, with the springs B, secured between them, theframes heilig connected by the cross bands F, covered or enclosed by anysuitable fabric E, and the upper frame supporting the seat or mattressD, the whole being alranged substantially as and tor the purpose setforth.
